Ama-gantry cranes afakwe amathayi erabha(ama-RTG cranes) ayimishini ebalulekile kumatheminali amakhonteyina, amayadi ezimboni, nasezindaweni zokugcina izimpahla ezinkulu. Idizayinelwe ukuphakamisa nokuthutha imithwalo esindayo ngokuguquguquka okuphezulu, lawa ma-cranes anikeza ukuhamba nokusebenza kahle ezindaweni ezihlukahlukene. Ziwusizo ikakhulukazi ekuphatheni iziqukathi ezistakiwe, imishini emikhulu, nezinye izinto ezisindayo. Kulesi sihloko, sidingida imininingwane yama-gantry cranes athayiwe enjoloba, izici ezithonya intengo yawo, kanye nezinzuzo zawo zizonke zemisebenzi yezimboni.
♦ Amandla Okuphakamisa: Enye yezinto eziyinhloko ezithinta izindleko ze-i-gantry crane enethayi erabhaamandla ayo okuphakamisa. Ama-cranes anamandla aphezulu adinga izinto zokwakha ezinamandla, amamotho anamandla, nezici zokuphepha ezengeziwe. Isibonelo, u-50 ton gantry crane eyakhelwe ukuphatha imithwalo esindayo ngokwemvelo uzobiza kakhulu kunokhreni omncane oklanyelwe ukusebenza okulula. Ngokufanayo, ama-gantry cranes asebenza kanzima asetshenziswa ezigayweni zensimbi noma ezikhumulweni zemikhumbi adinga izingxenye eziqinisiwe, ezikhuphula kokubili izindleko zokukhiqiza nezokulungisa.
♦I-Span and Lifting Height: Ubude be-crane—ibanga phakathi kwemilenze yawo—nobude bokuphakama obuphezulu nakho kuthinta ngokuqondile inani layo. I-crane ene-span enkudlwana inikeza ukumbozwa kwezindawo zokusebenza ezibanzi, okubalulekile emayadini abanzi noma ezindlini zokugcina impahla. Ukwengeza, ukuphakama okuphakeme kokuphakamisa kwenza i-crane ikwazi ukupakisha iziqukathi noma ukuthutha impahla esindayo ezindaweni eziphakeme. Njengoba ubude nobude bukhuphuka, kanjalo nenani lensimbi, ubunkimbinkimbi bobunjiniyela, nezinhlelo zokulawula ezidingekayo, konke okunomthelela ezindlekweni eziphelele ze-crane.
♦ Izidingo Zokwenza ngokwezifiso: Imisebenzi eminingi idinga ai-gantry crane enethayi erabhaeyenzelwe ukuhlangabezana nezidingo ezithile. Ukwenza ngendlela oyifisayo kungase kuhlanganise okunamathiselwe okukhethekile kokuphakamisa, amasistimu okulawula athuthukile, noma ukuguqulwa ukuze kuhambisane nezakhiwo ezingajwayelekile endaweni. Nakuba ukwenza ngokwezifiso kungakhuphula intengo, kuqinisekisa ukuthi i-crane ihlanganisa ngaphandle komthungo nokugeleza komsebenzi, ithuthukisa ukusebenza kahle nokusebenza kahle. I-crane yangokwezifiso eklanywe kahle ivamise ukuletha imbuyiselo esheshayo ekutshalweni kwezimali ngokunciphisa isikhathi sokuphumula kanye nokwandisa ukusebenza.
♦ Izici Zokuhamba: Amasistimu okuqondisa athuthukile angesinye isici esibalulekile emalini. Isibonelo, i-crane efakwe isistimu yokuqondisa enamasondo amane inikeza ukulawuleka okukhulu uma kuqhathaniswa nesistimu enamasondo amabili, okuvumela opharetha ukuthi baphathe imisebenzi eyinkimbinkimbi ezindaweni ezivalekile. Ama-cranes ama-gantry afakwe amathayi erabha anezici zokuhamba ezinemba okuphezulu abaluleke kakhulu ezindaweni lapho ukubekwa okunembayo kweziqukathi noma okokusebenza kubalulekile.
♦Indawo yokusebenza: Indawo osebenza kuyo u-crane nayo ithinta izindleko. Ama-cranes asebenza ngaphansi kwezimo ezinzima, njengamazinga okushisa adlulele, izindawo ezisogwini ezinokuchayeka kukasawoti, noma amasayithi anempahla egqwalayo, adinga izinyathelo zokuvikela ezengeziwe. Lokhu kungase kuhlanganise okunamathelayo okumelana nokugqwala, amasistimu kagesi avaleleke, noma izingxenye ezithuthukisiwe zama-hydraulic, ezinikela enanini lilonke kodwa ziqinisekise ukwethembeka nokuphepha kwesikhathi eside.
♦ Ukuthumela kanye Nokufakwa: Izindleko zokuhamba nezokufaka ngokuvamile azinakwa kodwa zingaba zibalulekile. Uma i-crane inkulu, izindleko zokuthumela zikhuphuka kanye nenqubo yokufaka inkimbinkimbi. AbanyeUmsebenzi osindayo we-gantry craneszidinga ukusekelwa kwezabasebenzi okukhethekile noma kobunjiniyela ngesikhathi sokuhlanganisa, okwengeza inani lezindleko. Ukuhlelela ukuhanjiswa nokufakwa kusenesikhathi kungasiza ekuthuthukiseni izindleko futhi kunciphise ukubambezeleka emigqeni yesikhathi yephrojekthi.
Kafushane, inani lentengo ai-gantry crane enethayi erabhakuthonywa izici eziningi, okuhlanganisa amandla okuphakamisa, ubude besikhathi, ubude bokuphakamisa, ukwenza ngendlela oyifisayo, izici zokuhamba, indawo yokusebenza, kanye nezidingo zokufaka. Ukukhetha i-crane elungile, efana ne-50 ton gantry crane noma ezinye izinketho ezisindayo, kuqinisekisa ukuthi indawo yakho ingasebenza ngokuphepha nangempumelelo ngenkathi uphethe imithwalo enzima. Ukutshala imali ku-gantry crane yekhwalithi ephezulu ehambisana nezidingo zakho zokusebenza akugcini nje ngokuthuthukisa umkhiqizo kodwa futhi kunikeza ukwethembeka kwesikhathi eside, okuyenza ibe yisixazululo esihlakaniphile nesingabizi kakhulu semisebenzi yesimanje yezimboni.
